What I claim is:

1. In a huller gin, a saw cylinder, a set of huller ribs disposed between the saws, said ribs being curved at their upper parts to extend into the huller breast and across the peripheries of the saws, each rib having straight edges on its opposite sides lying in a plane tangent to the curves at the points of intersection thereof with the peripheries of the saws, each of said parts being bevelled in opposite directions from said straight edges to provide gradually increasing clearances into the huller breast and. roll box of the gin of the cotton moved by the saws into said upper parts.

2. A huller rib for cotton gins having its upper part curved to extend acrossthe periphery of a gin saw into the huller breast of the gin, said part having substantially parallel straight edges v.said part having substantially parallel straight edges lying in a plane tangent to the curve at its point of intersection with the periphery of the saw, and being bevelled forwardly to provide with corresponding parts of similar adjacent huller ribs gradually increasing clearances into the huller breast of the cotton moved by the saws into'the spaces between straight edges of adjacent' ribs.
